IMPROVEMENT IN PHOTOGRAPHERS HEAD-RESTS.

Specification forming part of Letters Patent No. 42,650, dated May 10, 1864.

of the` same, reference, being had to the accom-` panying drawings, forming part of this speciication, in which- Figure lis a front elevation ot' my improved head-rest. Fig. 2 is a vertical section of the same at right angles to Fig. 1. Fig. 3 is a plan ot' the same.

Similar letters of reference indicate corresponding parts in all the figures.

The photographic head rests at present in use are very apt to show either their base on the floor or their rods between or at the sides of the legs in the picture of a standing male ligure. lhe principal object of myinvention is to prevent such exhibition, and to render the rest invisible when used; and to this end it consists in constructing the lower portion of the rest of two dat standards and a crosshead containing a socket, combined in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A A are the two standards, and B the crosshead. The standards are ot castiron, substantially of the form of the letter H, each having two feet, and have screws a a at their upper ends, with shoulders b b below them forthe support of the crosshead B. The crosshead has holes near its ends for the reception otl the upper parts of the standards, and is secured upon the standards by hand-nuts c c, which screw onto the screws a a.

D is the central or sliding rod, fitted to the socket which is provided in the center ot' the cross-head C. d d are the ratchet-teeth eut on the back ot' the said rod, and e is a springpawl attached to the socket ofthe cross-head to engage in the said ratchet-teeth, and thereby support the rod D after it has been adj usted to the proper height, and until the setscrewfin the socket can be screwed up. This set-screw merely serves to steady the rod D, the weight of the said rod being supported by the pawl independently ot' the set-screw. The head-piece E is fitted, adjusted, and secured in the rod D in the usual manner.

The standards A A being set edgewise toward the focus of the camera, and being so arranged as to be concealed by the legs ofthe figure, do not appear in the picture. By slack,- ening the set-nuts c c the standards may be turned and adjusted in the cross-head,so that wha-te\ er the angle at which the picture is taken the said standards may be concealed by .bein g set ed gewise toward the t'ocus.

The holes in the cross-head which receive the screws a a are elongated in such a manner as to provide for the adjustment of the standards in a backward and forward direction.

What I claim as my invention, and desire to secure by Letters Patent, is

The stand composed of two tlat standards, A A, and a cross-head, B, in which the said standards are adjustable, substantially as and for the purpose herein specified.
